For filling reaction and washing towers and the like a large series ofdifferent filling bodies of the most diverse geometrical shape andconstructed of the most diverse materials I have been suggestedpreviously. Such filling bpdies can be inserted into the reaction bodyelther in a regular arrangement or may be arranged therein irregularly.

It has now been found that a saddle like 310 sha e of the reactionbodies is very suitable an produces a particularly large washingsurface. It is particularly advanta eous if these shapes are so selectedthat t ey are substantially as wide as they are high. It

M has also been found of particular advantage to provide the saddleshaped bodies either with discharging grooves or with holes or withboth. For this ur ose they may for examplebe constructed of wirenetting. Ac-

92 cording to a further form of construction of the invention theshapes, by means of suitable operations, as for example by slightlypressing together the ends or by the application of suitableprojections, ribs or the like, may

also be so shaped that the reaction bodies are prevented from slidingone into the other.

Two or more suitably shaped bodies placed parallel to one another and ata predetermined distance apart may also be assembled tld to form asingle unit.

lln the accompanying drawing are illustrated by way of example a fewforms of construction of the filling bodies according to the presentinvention.

Figures 1 to 1 show saddle shaped filling bodies having substantiallythe same dimensions in length and width. Figure 1 is a" front elevation,Figure 2 a side elevation, Figure 3 a plan and Figure 1 a section on theline A-B of Figure 3.

Figures 5 to 8 show a filling body provided with small projections.Figure 5 shows a front elevation, Figure 6 a side elevation, Figure 7 aplan and Fi re 8 a. section on the line CD of Figure Figures 9 to 12show a filling body provided with ribs. Figure 9 is a front elevation,Figure 10a side elevation, Figure 11 a plan and Figure 12 a section ontheline E-F of Figure 11.

accompanying drawings there is provided a filling bod a having the sha eof a riding saddle. The body is formed rom a circular blank which isfolded upon itself in arcuate formation to form the downwardly bent lugsI) and b which correspond to the saddle leaves and reversely folded in aplane at right angles to the first fold to provide twoupwardly bent lugsc and c which correspond to the front pad and rear pads of the saddleseat. Inotlier Words the circular body is subjected to a crosswisereversed compressing or folding.

On the curved inner surface of the constructional forms according toFigs. 1-4, holes are provided at certain distances apart while theconstructional forms according to Figures 5-8 show pegs e provided onthe saddle face. Figures 9-12 show constructional forms provided withribs 7 and Figures 13-16 with parallel grooves g. The last named groupshows that the primary shape may also be modified in that the lugs bentin crosswise opposite directions are more or less pressed together. Fig.15 shows how the two lugs c and 0' are relatively com pressed in theircenter. The filling body according to Figs. 17-20 comprises two singlebodies a and a and is formed by uniting gwo single bodies oncorresponding flanged aces.

It has been found that filling bodies of the present invention whichshow as primary shape a crosswise reversed compressed circular area of aform resembling a riding saddle occupy considerably less space and havea much larger working surface. Filling bodies according to the inventionhave especially the advantage that they do not require to be regularlyfitted into the reaction chambers as according to the hitherto usualgeometrical molded bodies but may be loosely and irregularly filled in.The attainable reaction surface is almost double and if necessary morethan double the surfaces attainable with the usual filling bodies. Thevery thin structure also permits a very tight and secure fitting in thereaction vessels. Owing w to the peculiar saddle shape the gas streamsare continually deflected and always come in contact with irrigatedsurfacesan action or effect which could only be very inadequatelyattained with the usual types. For instance,

15 in cylinder bodies the gases rise within the cylinder and occupy theupper positions while the liquid moves on to the lowest positions and isthereby only in inadequate contact with the gas.

go Such saddle shaped reaction bodies may be placed into the chamber inan irregular manner. They form an extremely large surface and, by reasonof the constant change in direction in the flow of streams of gas or asliquid, an excellent means for promoting chemical and physicaloperations such as increasing the speed of reaction on stationarysurfaces, extraction and mixing operations between liquids and liquids,between liquids 80 and gases and between gases and gases in the mostfavourable manner.

The reaction bodies themselves may be constructed of the most diversematerial according tochemical and mechanical require- 85 ments and mayalso be constructed in difierent sizes.

I claim 1. A filling body for reaction and washing towers and the like,formed from a circular 40 blank folded in a crosswise reversed manner toresemble a riding saddle, the height and breadth being substantiallyequal.

2. A filling body according to claim 1 having apertures therein.

45 3. A filling body according to claim 1 wherein the saddle portion isprovided with enlargements.

4. A filling body according to claim 1 wherein the opposed foldedportions are so slightly bent towards one another adjacent their outeredges.

5. A filling body for reaction and washing towers and the likecomprising a plurality of saddle shaped elements assembled parallel to55 one another and held at suitable distances apart, the saddle shapedelements forming an integral unit.

In testimony whereof I affix my signature.
